2、 安装与配置
安装
#tar –zxvf log4cplus-1.0.4.2.tar.gz
#cd log4cplus-1.0.4.2
#configure --prefix=/usr/local/
#make
#make install //目的将文件放到/usr/local/lib/和/usr/local/include/log4cplus

这里已经安装成功，默认的路径lib库路径是/usr/local/lib/，头文件的位置：/usr/local/include/log4cplus
将/usr/local/lib下的和log4cplus相关的库都拷贝到/usr/lib
将头文件加到/etc/profile/ 设置一下环境变量
